Obito Uchiha

a rogue ninja

Obito first appears in "Kakashi Chronicle", a Naruto side story. A child living through the Third Great Ninja War, Obito (Kakashi's teammate on Team Minato) wanted to become the Hokage of Konohagakure, and had an unrequited love for his teammate Rin. When he and Kakashi rescue the kidnapped Rin during a mission, Obito's right side is crushed by a boulder following a cave-in. Thinking he was going to die, Obito had Rin transplant his left Sharingan into Kakashi to replace Kakashi's lost left eye. Obito's death has a profound effect on Kakashi; he begins taking on his mannerisms such as showing up late to everything and adopts Obito’s philosophy of how those who abandoned their comrades are "worse than scum".[13][14] Late in Part II of the manga, it is revealed that Obito was saved by an elderly Madara Uchiha and outfitted with prosthetics. He becomes Madara's apprentice, and Madara has Obito witness Rin's death at the hands of a reluctant Kakashi to break his spirit. Concluding that he can use the power of the Tailed Beasts to destroy the current reality and create a utopia, Obito adopts Madara's name and disguises his voice after the ninja's death; he then arranges similar events for Nagato with Yahiko's death to create the current incarnation of the Akatsuki.[15][16] While Kushina Uzumaki (then jinchuriki of Kurama, the Nine-Tails Kyuubi), is giving birth to Naruto Uzumaki, Obito mounts an attack on the Leaf Village, Konoha. He releases the seal over the Kyuubi from Kushina while she is weak during birth, and places the Nine-Tails under his control, releasing it on Konoha to tear the village apart and wreak havoc. During his infiltration, he encounters his former mentor Minato Namikaze (the fourth Hokage) and they fight. Minato defeats Obito, and releases Kurama from Obito's control. Obito then flees, leaving Konoha to deal with the Nine-Tails, resulting in Minato and Kushina's deaths.[17][18] The character has a behind-the-scenes role in the first half
